47Driver and Passenger Safety
Your vehicle’
s exhaust contains
carbon monoxide gas. You should
have no problem with carbon
monoxide entering the vehicle in
normal driving if you maintain
your vehicle properly. Have the
exhaust system inspected for leaks
whenever:
•The vehicle is raised for an oil
change.
•You notice a change in the
sound of the exhaust.
•The vehicle was in an accident
that may have damaged the
underside.
Carbon monoxide gas is toxic.
Breathing it can cause
unconsciousness and even kill
you.
Avoid any enclosed areas or
activities that expose you to
carbon monoxide.
High levels of carbon monoxide
can collect rapidly in enclosed
areas, such as a garage. Do not
run the engine with the garage
door closed. Even with the door
open, run the engine only long
enough to move the vehicle out of
the garage.
With the tailgate glass open, air
flow can pull exhaust gas into the
interior. This can create a
hazardous condition. If you must drive with the tailgate glass open,
open all the windows and set the
heating and cooling system as
shown below.
If you must sit in your parked
vehicle, even in an unconfined
area, with the engine running,
adjust the heating and cooling
system as follows:
1. Slide the lever to .
2. Turn the dial to
mode.
3. Turn the fan on high speed.
4. Set the temperature control to a comfortable setting.

This is a reminder that the fuel fill
door is on the left side of the
vehicle. Always park with that
side closest to the service station
pumps.
Engine Coolant
Temperature Gauge
When the key is in the “ON”
position, the engine coolant
temperature gauge indicates the
temperature of the engine coolant.
The letters “
C” and “H” on the
gauge represent “Cold” and
“Hot,” respectively.
NORMAL RANGE OVERHEATING
The gray area indicates the
normal engine coolant
temperature.
If the pointer reaches the
“
H”
mark, pull safely to the side of the
road. Turn to page 217 for
instructions and precautions on
checking the engine ’s cooling
system.

Driving with the temperature
gauge pointer at “
H” can cause
serious damage to the engine.

11 9Comfort and Convenience Features
The heating and air conditioning
system in your vehicle provides a
comfortable driving environment
in all weather conditions.
The audio system has many

120Comfort and Convenience Features This system combines heating and
cooling capabilities for comfort in
all weather conditions.
During air conditioning operation,
slight increases and decreases in
engine speed/power may be
noticed. This is normal, as the
system is designed to cycle the
compressor
ON and OFF to
maintain desired cooling. The
reduced compressor operation
should benefit fuel economy.
Air Conditioning Switch
Push this switch to operate the air
conditioning system. The light-
emitting diode in this switch lights
to show the system is operating.
To turn off the air conditioning,
push this switch in again.
Air conditioning will not operate
without the fan control lever in
one of the “
ON” positions.

169Driving Tips
Wheel Replacement
Considerations
Damaged wheels must be
replaced. For example, replace
wheels if they are bent, cracked or
heavily rusted, or if wheel nuts
often become loose. Also replace
wheels that leak air (except some
aluminum wheels that can be
repaired). See your Honda dealer.
Do not use bent wheels that have
been straightened, and do not use
tubes in leaking wheels designed
for tubeless tires. Such wheels
may have structural damage and
could fail without warning.
Maximum loads, maximum
inflation pressures, wheel
identification codes, and wheel
sizes are stamped on each wheel.
Service-tested and approvedwheels are available from your
Honda dealer.
When obtaining wheels for any
reason from any other source, the
replacement wheels should be
equal in load capacity, inflation
pressure capacity, diameter, width,
offset and mounting configuration
to those originally installed on
your vehicle. A wheel of the
wrong size or type may adversely
affect load carrying capacity,
wheel and bearing life, brake
cooling, speedometer/odometer
calibration, stopping ability,
headlight aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the body
and chassis. Replacement with
used wheels is not advised: They
may have been subjected to harsh
treatment or very high mileage and
could fail without warning.
Installing wheels and/or tires that
have a higher load carrying limit
than those that originally came on
your vehicle does not increase the
GAWR or GVWR of the vehicle.

195Care and Maintenance
This section explains why it is
important to keep your vehicle
well maintained and to follow
basic maintenance safety
precautions.
This section also includes
Maintenance Schedules for
normal driving and severe driving
conditions, a Maintenance
Record, and instructions for
simple maintenance tasks you
may want to take care of yourself.
If you have the skills and tools
required
to perform more complex
maintenance tasks on your Honda,
you may want to purchase the
Service Manual. See page 253 for
information on how to obtain a
copy, or see your Honda dealer. Service Station Information

The engine cooling system is
designed to maintain the engine at
the proper operating temperatures.
The cooling system was filled at
the factory with a quality engine
coolant. The engine cooling system
is designed to use coolant (a
mixture of water and ethylene
glycol antifreeze) rather than plain
water. The engine coolant solution
should be used year-round. It has
many advantages such as:
•provides freezing protection as
low as –33
F (–36
C)
• provides boiling protection up
to 262
F (128
C)
•protects against rust and
corrosion in the cooling system
• maintains the proper engine
temperature for efficient
operation and emission control
•allows proper operation of the
engine coolant temperature gauge See the Maintenance Schedule in
this section to find out when the
engine coolant must be replaced.
Checking the Coolant Level
Check the engine coolant level at
the interval shown in the
Maintenance Schedule unless there
is evidence of leaking or
overheating. The engine coolant
level should be between the
maximum and the minimum level
marks on the radiator reserve tank.
